A method is provided in one example embodiment and may include receiving an interest packet at a network element, wherein the interest packet identifies content requested by a consumer; determining whether a temporary face identifier (ID) contained in the interest packet is stored at the network element; and forwarding the interest packet to another network element based on a determination that the temporary face ID is stored at the network element, wherein the temporary face ID is associated with a face of the network element connected to the other network element.

System and method to bypass the forwarding information base (FIB) for interest packet forwarding in an information-centric networking (ICN) environment

In one implementation, a method includes transmitting, to a server, a first interest message. The first interest message includes a request for a representational state transfer (REST) operation and a name of a first state for the REST operation. The method also includes receiving, from the server, a second interest message. The second interest message includes the name of the first state for the REST operation. The method further includes transmitting, to the server, the first state based on the second interest message and receiving, from the server, a response to the REST operation.

Representational state transfer operations using information centric networking

Embodiments include technologies for identifying an equivalence class identifier in a packet received by a node configured to perform information centric networking (ICN) in an ICN network, where the packet includes a name identifying content associated with a producer node in the ICN network. Embodiments also include determining an equivalence class for the packet by determining a name prefix of the name based, at least in part, on the equivalence class identifier. Embodiments further include taking an action affecting a particular packet, the action based, at least in part, on the equivalence class. In specific embodiments, the name includes a plurality of name components, and the equivalence class identifier is a count indicating a number of name components in the name to be grouped together to determine the name prefix. In further embodiments, the number is greater than a particular number of name components in a routable name prefix.

Flow classification for information centric network protocols

In one embodiment, path routing in a node fabric of an information-centric network (ICN) includes transmitting a request from a source application to an upstream node via node faces of nodes in the node fabric along a path encoded in a Path Steering Value (PSV); and receiving at the source application from the upstream node a reply that travels along a return path encoded in the PSV. The PSV is generated by pairwise encoding pairs of node faces successively traversed by the reply and is represented by a deterministically decodable pairing function. Node face identifiers can be deterministically, i.e., uniquely, decoded from the PSV. The deterministically decodable pairing function is selected from a Cantor function, a Hopcroft and Ullman variant of the Cantor function, Hilbert curve algorithm, Morton code, and a bitwise pairing function.

Interest message path steering and multi-path traceroute in information-centric networking

Aspects of the disclosure are directed to systems, network nodes, and methods performed in a network node. A network node can host a TCP/ICN proxy for routing TCP packets through an ICN network. The network node can serve as a forward proxy or a reverse proxy. As a forward proxy, the network node can receive a first packet at the network node, the first packet compliant with a Transmission Control Protocol (TCP) protocol; encapsulate one or more TCP headers from the first packet into a payload field of a second packet, the second packet compliant with an Information Centric Networking (ICN) protocol; and transmit the second packet to a destination through an ICN network. As a reverse proxy, the network node can receive an ICN packet from an ICN network, decapsulate the ICN packet to its TCP components, and transmit the TCP packet through a TCP network.

Carrying TCP over an ICN network

In one implementation, a method includes receiving, from a link owner, a first interest message for an authorized link object, wherein the authorized link object links to content of a content owner. The method also includes transmitting, to the link owner, a second interest message for a proposed link object based on the first interest message. The method further includes receiving, from the link owner, the proposed link object, wherein the proposed link object comprises a first signature generated by the link owner. The method further includes determining whether the link owner is allowed to link to the content and transmitting, to the link owner, the authorized link object when the link owner is allowed to link to the content, wherein the authorized link object comprises a first name for the content, the first signature, and a second signature generated by a content owner.
